RO sanitization is a complete cleaning and disinfection process of the RO water purifier system to ensure safe, pure, and hygienic drinking water. It involves sanitizing the storage tank, filters, membranes, pipes, and faucets to remove bacteria, viruses, algae, and harmful contaminants that accumulate over time. Regular RO sanitization improves water taste, maintains purification efficiency, prevents foul odor, and protects your family’s health by ensuring consistently clean and safe drinking water.
